Conestoga Capital Advisors, an asset management company, released its second-quarter 2026 investor letter. A copy of the letter can be downloaded here. The letter reports a positive market shift towards Small Caps, with the Russell 2000 Index achieving its best first half since 1991 and the Russell 2000 Growth Index up 25.7% in Q2, fueled by AI enthusiasm and semiconductor stocks. However, market leadership was uneven, mirroring the Tech Bubble, with high-beta stocks outperforming while high-quality companies lagged, which impacted Conestoga’s quality-focused strategies. Management expressed confidence in long-term outcomes, noting that speculative leadership won’t last as monetary policy tightens and market breadth improves. The firm remains committed to high-quality growth businesses, expecting these to regain favor as leadership broadens. The Conestoga Small Cap Composite returned 14.32% net-of-fees in the second quarter, with 25.71% for the Russell 2000 Growth Index. Narrow Index leadership hurt the relative results, but it also hid Composite improvements. In addition, please check the Strategy’s top five holdings to know its best picks in 2026.
